Description

[Detailed description of the invention] The present invention includes a device that forcibly pulls and divides planted culms into objects to be reaped and objects to be reaped on the side of a horizontally rotating pulling device; Regarding a combine harvester that is equipped with a guide for guiding the object to be cut from a forced pulling weeding device to the pulling device, and a contact sensor for detecting culm length is provided in the pulling path of the pulling device, the original configuration of the combine It is an object of the present invention to simplify the mounting structure of the sensor by effectively utilizing the member as a mounting member.

The present invention is a combine harvester officially registered in which the sensor is attached to the guide, so there is no need to provide a separate support member for the sensor, and the above-mentioned object can be achieved distantly.

EMBODIMENT OF THE INVENTION Below, the embodiment of this invention is demonstrated based on illustrative drawing.

To configure the pre-processing section installed in the combine harvester, a frame body 3 is extended forward from the main body in which a threshing device 2 is mounted on a crawler-type traveling machine stand 1, and a weed pulling device A for the planted culm is constructed.
1. A clipper-type reaping device 4 for reaping the pulled husks, a device 5 that supplies the stock side of the pulled husks to the reaping device 4, and a device 5 that supplies the cut husks to the starting end of the threshing feed chain 6 toward the rear of the machine. A vertical conveying device 7 transports the cut husk, and a vertical conveying device 7 transports the cut husk.
A device 8 is attached to the frame 3 for conveying the machine in the direction of the lateral force towards the starting end of the machine.

To configure the weed pulling device A, as shown in FIGS. 1 and 2, an endless chain (not shown) equipped with a plurality of culm locking and conveying claws 9 is wound horizontally. The lifting devices 10a and 10b configured to be driven are disposed on the left and right sides of the lifting path B to constitute a horizontally rotating type lifting device 11, and an endless drive device equipped with a plurality of culm locking and conveying claws 12... A forced pulling and weeding device 13 configured to vertically wind and drive a chain (not shown) is disposed on the lateral outer side of the pulling device 11, and the culm from the pulling and weeding device 13 is A guide 14 is provided to guide the pulling device 11, so that the planted culms are forcibly separated from the front of the pulling device 11 into objects to be reaped and objects not to be reaped by the pulling device 13. As the aircraft moves forward, the guide 1
The lifting device 11 is configured to apply a lifting action to the object to be reaped which has been guided from the lifting device 3 along the line 4.

In order to configure the vertical conveyance device 7, a device 15 is provided which inherits the stock side of the shell culm from the horizontal conveyance device 8 and pinches and conveys it toward the starting end of the feed chain 6, and a device 15 is provided which transfers the stem side of the shell culm to the starting end of the feed chain 6. A device 16 is provided which takes over from the pulling device 11 and locks and conveys the feed chain 6 toward the starting end.

The positions of the two conveyance devices 15 and 16 on the conveyance start end side relative to the horizontal conveyance device 8 and the lifting device 11 are configured to be swingable in the culm direction around the horizontal axis X on the conveyance end side thereof, By the swinging operation, the gripping position of the clamping and conveying device 15 relative to the culm inherited from the horizontal conveying device 8 is changed, and the handling depth in the threshing device 2 is changed and adjusted.

A device 17 for detecting the length of the culm in the weed pulling device A and a fluid pressure cylinder 18 for swinging the vertical conveyance device 7 are provided, and a fluid pressure cylinder 18 for swinging the vertical conveyance device 7 is provided. control valve 19
A control device 20 is provided to operate the culm, and the handling depth is automatically adjusted based on the detection of the culm length of the raised shell culm.

That is, as shown in FIGS. 2 and 3, the culm length detecting device 17 includes a sensor 21 that detects the presence of a culm by contact with the culm and oscillation of the culm. It comprises a contact sensor 23 equipped with a switch section 22 that transmits a detection result of the presence of a culm as it moves,
The three device sensors 23 are attached to the guide 14 with their respective sensor pars 21 protruding above the lifting path B and being arranged in parallel in the culm direction, Consideration has been made so that the guide 14 can also be used as a sensor support member.

The control device 20 includes the culm length detection device 17.
A culm presence/absence detection device 2 similar to the contact sensor 23 in
4 is attached to the lower part of the left pulling device 10a, and is configured to become operable based on the culm presence detection signal from this detection device 24, and all sensor parts in the culm length detection device 17 21... swings, it is determined that the culm length of the object to be reaped is longer than the standard, and the control valve 19 is operated to a position where the cylinder 18 is driven in the direction of swinging the vertical conveyance device 7 toward the tip side. However, when only the lower two of all the sensor pars 21 swing, it is determined that the culm length of the object to be reaped is standard, and the control valve 19 is operated to the neutral position, and
When all the sensor pars 21... become non-swinging state or when only the lowest one among them swings, it is determined that the culm length of the object to be reaped is shorter than the standard, and the vertical conveyance device 7 is moved to the plant base side. The control valve 19 is operated to a position where the cylinder 18 is driven in a direction in which the cylinder 18 is swung.
